接触网设备电气烧伤的原因与防治

接触网设备电气烧伤的主要原因，是线索允许的持续载流量不足，主导电回路接触不良和非正常电气设备分流等。针对存在的问题，提出了更新载流量偏小的线索，优化运输组织，避免牵引电流过大，加强对特殊部位的安装防护，加强检查处理，对电连接线等设备采用定期更换等防治措施。     

Parallel-pipelined architecture of H.264 deblocking filter with adaptive dynamic power

In H.264,the computational complexity and memory access of deblocking filter are variable and depend on the video contents. In this paper,a pipelined VLSI architecture of deblocking filter with adaptive dynamic power is proposed. It avoids redundant computations and memory access by precluding the blocks which can be skipped. And the vertical and horizontal edges are simultaneously processed in an advanced scan order to speed up the decoder. As a result,the dynamic power of the proposed architecture can be ...
